Hey im really confused as to how to calculate the flexible budget costs and what the formula is. Thank you

Schuyler Electric Inc. manufactures lamps. (Click the icon to view the standards.) The number of finished units budgeted for January 2018 was 9,710; 9,650 units were actually produced (Click the icon to view actual data.) Assume that there was no beginning inventory of either direct materials or finished units. During the month, materials purchases amounted to 97, 100 kg, at a total cost of $495,210. Input rate variances are isolated upon purchase. Input-efficiency variances are isolated at the time of usage Required 1. Compute the January 2018 rate and efficiency variances of direct materials and direct manufacturing labour. 2. Prepare journal entries to record the variances in requirement 1. 3. Comment on the January 2018 rate and efficiency variances of Schuyler Electric. 4. Why might Schuyler calculate direct materials rate variances and direct materials efficiency variances with reference to different points in time? More info .. Actual results in January 2018 were: Requirement 1. Compute the January 2018 rate and efficiency variances of direct materials and direct manufacturing labour. Direct materials: 95,000 kg used Direct manufacturing labour: 4,800 hours Let's begin by calculating the actual input at the budgeted rate. (Round your answers to the nearest whole dollar.) $ 150,000 - Cost Actual input 97,100 Budgeted rate $ 5.00 $ 485,500 Direct materials (purchases) Direct materials (usage) 95,000 x $ 5.00 $ 475,000 - X More info Direct manufacturing labour 4,800 x $ 30.00 $ 144,000 Next determine the formula and calculate the costs for the flexible budget. Flexible budget cost It has set up the following standards per finished unit for direct materials and direct manufacturing labour: Direct materials Direct manufacturing labour Direct materials: 10 kg at $5.00 per kg $ 50.00 Direct manufacturing labour: 0.5 hour at $30 per hour 15.00
